A post claiming an OpenAI researcher described an Anthropic colleague's extreme reaction to the Mythos model exploded to 3,062 upvotes and 269 comments on r/ClaudeAI, the highest-engagement post across all AI subreddits today. Anthropic's Claude Mythos — reportedly ~10 trillion parameters — was confirmed after a March 26 data leak exposed an unsecured draft blog post. The model has been deployed in a limited cybersecurity initiative (Project Glasswing) after discovering thousands of zero-day vulnerabilities across every major OS and browser, including a 27-year-old OpenBSD bug.
